3 Claims.

This invention relates to a mechanical toy simulative of a cock and adapted to imitate the crow thereof.

It is an object of the instant invention to provide a mechanical toy of simple and rugged construction.

A further object is to provide a relatively inexpensive toy.

Other objects of the instant invention will become apparent in the course of the following specication.

In the accomplishment of these objectives, the body of the toy is made in the form of a cock from any suitable material and is designed to stand upright. The crowing mechanism is inserted upwardly through the base of the body which may be hollow and comprises a gear train, the teeth of the last member of'which is in contact with the free end f a'vibrator, the opposite end of the Vibrator being attached to a sounding board forming the base of the crowing mechanism. 'A spring under unwinding tension maintains the gear train operative, the velocity of which is varied by a dual braking mechanism y,which in coaction with a handle for winding the spring varies the amplitude of the vibrations of the sounding board to give out the sound simulative of the cocks crow.

The invention will appear more cle-arly from the following detailed description when taken in connection with the accompanying drawing showing by way of example a preferred embodiment of the inventive idea. l

Figure 6 is a sectional view along the line 6 6 of Figure 2.

Figure 7 is an elevational view of the cam. Referring now in greater detail to the drawings in which like reference numerals indicate like parts, reference numeral I0 indicates the body of the toy cock, and II the crowing mechanism.

v The body of the toyV cock III-may be hollow formed from any suitable material, in two parts, if desired, and joined by any suitable means at the front and back at such points as I2 (Fig. 4). The base of the toy cock I0 is open and covered by the elliptical base cap I3 (Fig. 5) which is designedV to lit over the periphery of the base of the toy cock I0 as shown in Figure 4 to maintain it upright.

The crowing mechanism I I is inserted upward- 1y into the hollow body IIJ through the open base and is maintained therein by the previously mentioned base cap I3 and prevented from moving by the inside surface portion of the body I0 and the pin I4 described later. The crowing mechanism II comprises an outer cylindrical housing I5 and an inner rectangular housing I6 inserted therein. The outer cylindrical housing I5 may be made of any suitable material such as cardboard having a diameter adapted for insertion through the opengbase of the body I0, sulcient height to extend upwardly therein as shown in Figure 4, and with open top and bottom. The inner rectangular housing I6 may be made of metal or the like to provide suitable bearings for the later described gear train of the crowing mechanism II and of appropriate dimensions for insertion in the cylindrical housing I5 as shown in Figures 2 and 3. The inner rectangular housing IG is formed with the opposed front member I'I (Fig. 2), the opposed back member I8, and the opposed end members I9 and 20 (Fig. 3). At the base, the opposed front and back members Il and I8 are extended downwardly and outwardly to provide the supports 2| and 22 for the base of the outer cylindrical housing I5 as shown in Figure 2. At the top, the opposed front and back members I'I and I8 of the inner rectangular housing I6 are attached to the cylindrical housing I5 by the clips 23 and 24 (Fig. 2) which at one end are attached to the members I'I and I8 by any suitable means and at the opposite end turned down to fit over the top of the cylindrical housing I5 as shown also in Figure 2. In the opposed back member I8, at the base in Figure 2, is the cylindrical protuberance 25 which forms a part of the subsequently described centrifugal braking mechanism.

Within the inner rectangular housing I6 is a gear train formed with the driver 26, the intermediate gear 2'I, and the driven gear 28, the rotary motion of the driver 26 being imparted to the intermediate gear 2l through the pinion 29 keyed to the shaft 30, and the rotary motion of the intermediate gear 21 being imparted to the driven gear 28 through the pinion 3| keyed to the shaft 32. The driver 25 rotatably mounted on the shaft 33 which shaft is extended for- 3 wardly through the opposed front member I'I of the inner rectangular. housing I6, the wall of the outer cylindrical housing l5, and the body of the toy cock It to form a handle member 34. The spiral spring 35 is inserted around the shaft 33 and secured at the back to the opposed back member I8 of the inner rectangular housing IE and attached at the front to the driver 25 which is placed under the unwinding tension of the spiral spring 35. when the driver 26l is wound by the handle member 34 revolving the cam 39 as later shown. the outer cylindrical housing Ii the sounding board 3S is fitted and through which one end of the vibrator 3l is inserted as shown in Figure'3 Over the base of while the opposite end of the vibrator 37 is turned Y upwardly in contact with the teeth ofthe driven tion.

The crowing sound lis attained by varying the amplitude of the vibrations ofv thevibrator 31 which, in turn, is attainedby a dual braking mechanism and the handle member 34Y coacting with the gear train to vary the angular velocity thereof. The dual braking mechanism comprises the cam brake 37a and the centrifugal brake 38. The cam brakela comprises the cam 39 (Figs. 2 and 3) which is keyed to the shaft 33, the cam follower 4l) pivotally mounted on the shaft 4I, the top of which bears under tension against the cam 39 and the base against the brake wheel 42 keyed to the shaft 32 to apply a variable brakingpressure to the rotary lmotion of the gear train. The cam 39 also serves as the Winding mechanism and on which the lug 48 protrudes outwardly to coact with a corresponding lug 4l on the driver 23 so that as the handle member B- ber 34. From the wound psition, the handle member 34 is moved back to the unwound position. The driver 28y under the unwinding tension of the spring 35 imparts rotary motion to the pinion 29 and the intermediate gear 21 keyed to the shaft 3B. The intermediate gear 21 in turn imparts rotary motion to the driven gear 28 through the pinion 3lv both of which are keyed tothe shaft 32. The. rotary motion imparted to the teeth of the driven'gear 23 against theV vibrator 3'! under the limitations of the centrifugal brake 38 and the cam brake 3Ia wherein sufficient movement is given to the cam 39 by the handle member 34 to raise the follower 40 over the cam surfaces produces the variations in the vibrations which give the sound simulative of the cocksr crow.

It is app-arent that the specic illustrations shown above have been@ given by way of illustration and not by Vway Yof limitationv and thatthe structures above described are subjected to wide variation and modification without departingv from the scope or intent of the invention,V all of which variations and modifications are to be included withinthe scope ofthe present invention.

What is claimed is: Y l. A toy cock adapted to simulate acocks crow and comprising' a hollow body simulative of a cock, a crowing mechanism for the hollow body, the crovving mechanism comprising a vibrating diaphragm, a reed for the diaphragm, a gear train coacting with the reed,rthe gear train com.- prising` at least a driver and a driven member, a rotatable shaft for each of said members, means keying the driven member to the shaft, the driver 34 is rotated, the lug 48 in contact with the lug 4? on the driver 26 places the spiral spring 35 under unwinding tension.

The centrifugal brake 2.*3 comprises the two' brake shoes 43 and 44 pivotally mounted ontheY plate 45 which is keyed to the shaft 32 Vand designed to rotate therewith within thefcylindrical of the shaft 32 increases, the brake-i shoes 43 i` and 44 rotate outwardly and press against the inside surface portion of the drum 25 until the angular velocity is reducedv toA a point where the tension of the elastic member 46 is sufficient to rotate the brake shoes 43 and 44 awayfrom theV inside surface portion ofthe protuberance 2'5 serving as the brake drum.

The pin I4 (Fig. 2) isV passedthrough the opposed front and back members I1 and I8 of the inner rectangular housing I6, the Wall of the outer cylindrical housing I l and is extended outwardly to contact the handle member 34 when revolved through some 360 degrees. Y'
